Application October 16, 1948, Serial No. 54,944

3 Claims. (Cl. 248-58) Our invention relates to improvements in hanging supports, an object thereof being to provide a simple, durable and relatively inexpensive article of such nature, particularly though not exclusively for supporting clothes lines, the same being adapted to .be quickly, easily and s ecurely attached to and removed from exposed overhead `joists such as those customarily found in the basements or other unfinished areas of dwellings.

More specifically, it is an object of our invention to provide a hanging support of the instant nature comprising a hanger-bar and a clamp-bar adjustably tied thereto, whereby hanger-bar and vclamp-bar may be caused to engage the opposite vsides of a joist in jaw-like manner and securely grip such joist between them.

Another object of the invention is to provide a hanging support of the present character including a pair of hanger-bars with companion clampbars and an article-attaching rail secured to the hanger-bars in which such support the clamp bars may be alterably tied to the hanger-bars to enable the support to be hung from a single joist or from two spaced joists.

Other objects of the invention reside in the novel combination and arrangement of parts and in the details of construction hereinafter illustrated and/or described.

In the accompanying drawing, Fig. 1 is a perspective view of a support embodying our invention and shown as hung from a single overhead joist; Fig. 2 is a perspective view of the `hanging support shown in Fig. l, but with the parts thereof assembled for the attachment of the support to two spaced overhead joists; Fig.

3 is a perspective view in detail of a clamp-, bar used in association with a companion hangerbar, and Fig. 4 is a plan view of a hook which is applicable to the support for the attachment Aof an article thereto.

. Reference being had to the accompanying drawing, it will be seen that Figs. 1 and 2 show exposed overhead joists I such as those customarily found in conventional building construction.

The illustrated form of our improved support includes a pair of hanger-bars A of angle iron and a rail B of angle iron to which the lower ends of said hanger-bars A are rigidly secured. The fastening of the rail A to the hanger-bars B may be accomplished in any suitable manner, as by welding or otherwise, it being preferable that one of the flanges of-the rail B, as at II, stand upright. In fastening the hanger-bars A to the.

rail B, said hanger-bars are relatively disposed in "right and left relationship so that the flanges I2 thereof will occupy relatively remote disposition in a common plane, while the flanges I3 thereof will occupy relatively proximate disposition in parallel planes spaced apart a distance equal to the measurement between the opposite faces of adjacent joists IIJ. Each of the anges I 2, I3 of each hanger-bar A is formed therealong intermediately thereof with a number of bolt holes I4.

A pair of clamp-bars C of angle iron are supplied for cooperation With the hanger-bars A. These clamp-bars C are of right and left pattern. The ange I5 of each clamp-bar C is formed intermediately thereof with a bolt hole I6 therein, the lower terminal portion of such ange I5 being bent inwardly at right angles to the main portion thereof to provide a toe Il for fulcruming engagement with one or the other of the flanges I2, I3 of one of the hanger bars A when said main portion of the flange I5 of the clamp-bar C is disposed to confront the upper portion of such hanger-bar flange. To facilitate the bending of the flange I5 of a clamp-bar C, the other ange I8 of such bar is triangularly notched, the apex of the notch registering'with the line-of-bend in the ange I5 of said clampbar C.

AA pair of headed bolts I9 are supplied, each thereof being threadedly tted opposite its head with a binding nut 20. One of the bolts I9 serves to tie one clamp-bar C to vone hanger-bar A and the other bolt I9 serves to tie the other clampbar C to the other hanger-bar A. In each case,

4the bolt I9 will extend through the hole I6 in the flange I5 of the clamp-bar C and through one of the holes I4 in one of the flanges I2, 4I3 of the hanger-bar A with the head of the bolt I9 engaging the outer face of one of the flanges 'through which the bolt extends and the binding vnut 20 on the bolt I9 engaging the outer face of the other of said flanges.

To suspend the support from a single joist, as

-shown in Fig. 1, the tie-bolts I9 are extended I3 of the hanger-bar A when said clamp-bar C -is positioned relative'to thehanger-bar A with lthe toe portion I1 of its flange I5 fulcrumed against said flange I2 and with the main portion of its said flange I5 confronting said flange I2 of said hanger-bar A (Fig. l). With the clampbars C tied to the hanger-bars A by the bolts I8, the assembly is applied to a joist I with the upper portions of the flanges I2 of the hangerbars A confronting one face of the joist ID and with the upper portions of the flanges I5 of the clamp-bars C confronting the other face of said joist. Thereupon, the binding nuts on the bolts I9 will be tightened with the result that the upper portions of the clamp-bars C will be drawn toward the hanger-bars A and thereby cause said clamp-bars C and hanger-bars A to grip the joist rmly in jaw-like manner. From the foregoing it will be obvious that detachment of the support from the joist II) may be readily effected simply by loosening the `binding nuts 26 on the tie-bolts I9.

To suspend the support from two adjacent joists, as shown in Fig. 2, the tie-bolts I8 are eX tended through corresponding bolt holes I4 in the flanges I3 of the hanger-bars A and through the bolt holes I6 of the respective clamp-bars C selected for association with the respective hanger-bars A. In this case, the particular clamp-bar C selected for association with each hanger-bar A is the one whose flange I8 will lie in the plane of the flange I2 of the hanger-bar when said clamp-bar is Positioned relative to the hanger-bar with the toe portion I'I of its flange fulcrumed against said flange I3 and with the main portion of its said flange I5 confronting said flange I3 of said hanger-bar (Fig. 2).

To enable the tie-bolts I9 to underlie closelyVV the lower edge or edges of a joist or joists to which the support is attached and at the same i time enable the rail B to be positioned at various elevations, we provide said series of holes I4 in the flanges I2, I3 of the hanger-bars A for said tie-bolts I9. Obviously, the higher the holes I4 may be, which receive the tieV bolts I9, the lower will be the position assumed by the rail B.

Lines or other articles to be supported may be secured directly toV the rail B or hanger bars A in any suitable manner. As shown, apertures 2I formed in the upstanding flange II of the rail' B facilitate the attachment of articles to said rail and such apertures 2I also provide for the ready attachment to said rail B of hooks D constructed as shown in Fig. 4. This form of hook has a hooked head 22, shank 23 and a butt-stop 24 formed by making a return bend in the terminal portion of the shank 23, said form of hook being readily threaded into a rail-aperture 2I hooked-head foremost. Y

ln an alternate form of the invention, one or more of the hanger-bars A, with associated clamp-bar or clamp-bars C, will bev employed without an article attaching member such as the rail'B. In such case, each of the anges l2, I3 of each hanger-bar A will be formed near the lower end thereof with an aperture 25 adapted to receive a line or other article to be supported and adapted further to admit ofv the 'application thereto of an attaching hook of suitable construcf tion such, for example, as thatshown in Fig. 4.

Changes in the specific form of our invention as herein described, may be made within the scope of what is claimed without departing from the spirit of our invention.

Having described our invention, what we claim as new and desire to protect by Letters Patent is:
